TYSIM KR40A chobowola chaching'ono chozungulira chinagwira ntchito yomanga madera akumidzi ku Sichuan

TYSIM ikutenga nawo mbali pantchito yomanga madera atsopano akumidzi ku China potsatira mfundo zatsopano zakumidzi. Pakali pano, ndi kuchepa kwapang’onopang’ono kwa anthu osauka a m’dzikoli ndi miyoyo ya anthu otukuka, zofuna zatsopano zikuperekedwa pa kumanga nyumba, makamaka nyumba zomanga zomanga m’madera akumidzi, zomwe zayamba pang’onopang’ono kuchoka m’nyumba zakale zansanjika imodzi kufika pa 2-3 nkhani, ndipo ena afika pa 5 -7 pansi, zomwe zimafuna mulu kuti amange maziko a nyumbayo kuti akwaniritse zofunikira zamapangidwe apansi ndi kukwaniritsa zofunikira zapadera za chivomezi ndi kukana kusefukira kwa madzi.

M’madera akumidzi, misewu ndi yopapatiza, misewu yodutsamo n’njochepa, ndipo madera akale a m’tauni ali ndi mawaya amagetsi mothithikana, zomwe zimapangitsa kuti zitsulo zobowola zikhale zovuta kudutsa.

Izo sizingakhoze kokha kukumana mikhalidwe ya mayendedwe, komanso kukwaniritsa zomanga, ndi mwangwiro kuthetsa mavuto amenewa.

Makina obowola a rotary omwe adagulidwa ndi kasitomala nthawi ino adawonedwa nthawi yomweyo ndi makasitomala ambiri atangofika pamalo omanga. Pafupifupi, imatha kupanga zidutswa 8-10 patsiku, chilichonse chimakhala ndi kuya kwa 8-9 metres. Kumangako ndi kothandiza ndipo kumapangitsa makasitomala kukhala okwera mtengo kwambiri.
